.SH DESCRIPTION
.I Glarendx
computes the selected glare index
.I type
from the given
.I glarefile
produced by
.I findglare(1).

computes one value for each (indirect illuminance) angle in the input file.
If no
.I glarefile
is given,
.I glarendx
reads from the standard input.
The
.I \-h
option can be used to remove the information header from the output.
